Curtain Wall Systems

Stick, semi-structural, structural silicone and unitised facades

Curtain Wall Systems

Turnkey curtain walling for offices, hotels, shopping centres and residences, including design, fabrication and installation.

Priced per project

A curtain wall is a non-load-bearing outer wall that hangs in front of the structure and transfers its own weight and wind loads to the floors. At Rasyo we work with four main system types and decide together which one suits the building's height, look, programme and budget.

System types

  • Stick facade – CW50: Mullions and transoms are assembled on site and the glass is held by pressure plates and outer caps. Flexible and economical.
  • Structural silicone – CW52 SG: The glass is held by structural silicone with no visible outer profile, giving an uninterrupted glass surface.
  • Unitised – UC150: Storey-height panels are made and glazed in the factory, then lifted into place by crane. A fast, high-quality solution for tall buildings.

Engineering

On every project we calculate wind loads to TS EN 1991-1-4, check glass thickness and deflection, calculate anchor pull-out and design joints for seismic inter-storey drift. Thermal performance is reported as a Ucw value to EN ISO 12631.

Scope

System design, shop drawings, mock-up, fabrication, installation, on-site water testing and the as-built file all come under one contract. Our crews work with our own tower crane, mobile platforms and suspended cradles.

Scope of service

  • Structural and thermal calculation
  • Mock-up testing
  • Own installation crews
  • As-built file

Frequently asked questions

How do you choose between a stick and a unitised facade?
Building height, programme and site conditions decide. For buildings under 10 storeys with a flexible programme, a stick facade is economical. For 15 storeys or more, fast-track projects or city sites where scaffolding is impractical, a unitised facade offers an overall cost advantage.
Does thermally broken aluminium insulate as well as PVC?
The W80 HI series, with a wide polyamide break and foam fill, reaches Uf 1.4 W/m²K, close to a good PVC series. Aluminium's advantage is that it delivers this with much slimmer profiles and far larger sash sizes.
What do you need to prepare a quote?
Architectural floor plans, elevations and system sections (DWG or PDF), plus any specification and bill of quantities, are enough. You can upload your files through the project quote form, and we send a system proposal and budget range within five working days.
Why does pricing vary from project to project?
Glass type and size, profile sections driven by wind load, colour and finish, anchor conditions, building height and access method all affect cost directly. As aluminium and glass prices follow exchange rates, quotes are valid for 30 days.
Is a mock-up test needed on every project?
No. Test reports exist for our standard systems. But on tall buildings, bespoke details or where the specification requires it, we recommend a full-scale mock-up test. Its cost and duration are shown separately in the quote.
